Differences between git pull origin master & git pull origin/master

Question

What is the difference between git pull origin master and git pull origin/master ?

Answer 1

git pull origin master will fetch all the changes from the remote's master branch and will merge it into your local.We generally don't use git pull origin/master.We can do the same thing by git merge origin/master.It will merge all the changes from "cached copy" of origin's master branch into your local branch.In my case git pull origin/master is throwing the error.
